CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority from Provisional Application number 63/305,430, filed Feb. 1, 2022, the entire contents of which are hereby incorporated by reference.

FIELD OF THE INVENTION

The present disclosure provides a washing appliance for washing a device and methods of using the appliance.

BACKGROUND OF THE INVENTION

The estimated annual cost of waste in the US health care system ranges from $760 billion to $935 billion, accounting for approximately 25% of total health care spending, and the projected potential savings from interventions that reduce waste, excluding savings from administrative complexity, ranges from $191 billion to $286 billion, representing a potential 25% reduction in the total cost of waste. Further, medical waste constitutes a special class of hazardous pollutants causing serious environmental impact. The disposal of untreated health care wastes in landfills can lead to the contamination of drinking, surface, and ground waters if those landfills are not properly constructed.

Single-use medical device reprocessing is effective in reducing the volume of waste produced and reducing costs to hospitals and reduce the environmental impact of medical waste. On average, reprocessed single-use medical devices can offer 50% cost savings. There will continue to be a need for reprocessed single-use medical devices as the commercial reprocessing industry expands. A variety of devices for disinfection of surgical instruments, forceps, endoscopes, and other medical devices exist, all of which are used on devices that are not labeled single-use. The devices include autoclaves and endoscope reprocessing machines. However, there are currently no machines on the market that effectively disinfect single-use medical devices such as medical device used during cardiovascular procedures (cath lab) and accessory devices.

Therefore, there is a need for devices, machines, and methods capable of efficiently and effectively reprocessing single-use medical devices and accessory devices such as those used during cardiovascular procedures.

I. Washing Appliance

One aspect of the present disclosure encompasses a washing appliance for washing devices. The washing appliance comprises a rinse tank, manifolds for suspending devices to be washed in the washing appliance, and spray assemblies for spraying devices suspended in the rinse tank.

(A) Devices

The washing appliance of the instant disclosure can be used to wash any device, including single-use medical devices used during cardiovascular procedures (cath lab) and accessory devices. Accordingly, as used herein, the term “medical device” comprises a medical device used during a medical procedure and any other accessory that may be used during the procedure. In some aspects, the washing appliance is used to wash a medical device used during cardiovascular procedures (cath lab) and accessory devices. Non-limiting examples of medical devices and accessories include medical devices comprising lumens, catheters, endoscopes, dilators, dilator accessories, introducer sheaths, guidewires, balloons, vascular closure devices, atherectomy devices, fractional flow reserve (FFR) wires, racetrack tubing, cables and wiring, medical tubing, and hypodermic, transseptal, and other needles.

In some aspects, the medical device comprises one or more lumen such as catheters and endoscopes. Catheters and endoscopes are extensively used to perform an array of minimally invasive procedures. An endoscope is an illuminated optical, typically slender, and tubular instrument (a type of borescope) used to look deep into the body by way of openings such as the mouth or anus. Endoscopes use tubes which are only a few millimeters thick to transfer illumination in one direction and high-resolution images in real time in the other direction, resulting in minimally invasive surgeries. Endoscopes are used to examine the internal organs like the throat or esophagus. Specialized endoscopes are named after their target organ. Examples include the cystoscope (bladder), nephroscope (kidney), bronchoscope (bronchus), arthroscope (joints) and colonoscope (colon), and laparoscope (abdomen or pelvis). Endoscopes can be used to visually examine and diagnose or assist in surgery such as an arthroscopy. For non-medical uses, similar instruments are called borescopes. Some endoscopes comprise working channels comprising a lumen to allow entry of medical instruments or manipulators. As used herein, the term “lumen device” is used to refer to a medical device comprising a lumen and accessories used during procedures employing the lumen device.

A catheter is a thin tube made from medical grade materials serving a broad range of functions in medicine. Catheters can be inserted in the body to treat diseases or perform a surgical procedure. By modifying the material or adjusting the way catheters are manufactured, it is possible to tailor catheters for cardiovascular, urological, gastrointestinal, neurovascular, and ophthalmic applications. In most uses, a catheter is a thin, flexible tube (“soft” catheter) though catheters are available in varying levels of stiffness depending on the application. A catheter left inside the body, either temporarily or permanently, may be referred to as an “indwelling catheter” (for example, a peripherally inserted central catheter). A permanently inserted catheter may be referred to as a “permcath.” Catheters can be inserted into a body cavity, duct, vessel, brain, skin, or adipose tissue. Functionally, catheters allow drainage and administration of fluids or gases, access by surgical instruments, and can also perform a wide variety of other tasks depending on the type of catheter.

Placement of a catheter into a particular part of the body may allow:

-   Administration of fluids (i.e., heparinized saline, contrast dyes)     during an electrophysiology, or related, study; -   Fluid sampling during an electrophysiology, or related, study; -   Direct blood pressure measurement during an electrophysiology, or     related, study; -   Angioplasty, angiography, balloon septostomy, balloon sinuplasty,     cardiac, catheter ablation; -   Draining urine from the urinary bladder as in urinary     catheterization, e.g., the intermittent catheters or Foley catheter     or even when the urethra is damaged as in suprapubic     catheterization; -   Drainage of urine from the kidney by percutaneous (through the skin)     nephrostomy; -   Drainage of fluid collections, e.g. an abdominal abscess; -   Drainage of air from around the lung (pigtail catheter); -   Administration of intravenous fluids, medication or parenteral     nutrition with a peripheral venous catheter; -   Direct measurement of blood pressure in an artery or vein; -   Direct measurement of intracranial pressure; -   Direct measurement of blood flow; -   Intravascular ultrasound; -   Optical coherence tomography (OCT) imaging; -   Near-infrared spectoscopy (NIRS); -   Administration of anesthetic medication into the epidural space, the     subarachnoid space, or around a major nerve bundle such as the     brachial plexus; -   Administration of oxygen, volatile anesthetic agents, and other     breathing gases into the lungs using a tracheal tube; -   Subcutaneous administration of insulin or other medications, with     the use of an infusion set and insulin pump; -   Administering drugs or fluids into a large-bore catheter positioned     either in a vein near the heart or just inside the atrium; -   Measuring pressures in the heart; -   Inserting fertilized embryos from in vitro fertilization into the     uterus; -   Providing quick access to the central circulation of premature     infants using an umbilical line; -   Attaching catheters to various other devices; -   Hemodialysis using a double or triple lumen, external catheter; and -   Artificial insemination.

II. Method of Washing a Device

The instant invention also encompasses a method of cleaning a device comprising a lumen using a washing appliance described in Section (I) herein above. The device can be as described in Section I(a) herein above.

The method comprises attaching one or more devices to be washed to device attachment accessories of a manifold. The method can further comprise attaching device attachment accessories to the attachment points of the manifold appropriate for hanging the device or devices to be washed. After the one or more devices are attached to the manifold, the manifold is attached and optionally secured to the manifold support structure in the interior space of the rinse tank. The method further comprises washing exterior surfaces of the device by attaching the spray fluid opening of the spray assembly to a source of cleaning fluid by attaching piping extending from the spray fluid opening to the source of cleaning fluid and spraying the exterior surfaces of the device with cleaning fluid to thereby washing the exterior surfaces of the device. In some aspects, the method further comprises drying the exterior surface of the device by spraying the exterior surface with drying fluid.

In some aspects, the device is a lumen device. When the device is a lumen device, the method can further comprise cleaning the lumen of the device concurrently or sequentially with cleaning the exterior of the device. Clean the lumen of a lumen device can comprise attaching the wash fluid opening of the manifold to a source of cleaning fluid by attaching piping extending from the wash fluid opening of the manifold to the source of cleaning fluid. The method further comprises flushing the lumen of the device with the cleaning fluid at a predetermined flow rate or pressure. As with cleaning the exterior of a device, the lumen of the device can optionally be dried by flushing the lumen of the device with drying fluid. It will be recognized that in some aspects, only the lumen of the lumen device can be cleaned without also cleaning the exterior of the device. Accordingly, a method of cleaning a lumen device can comprise cleaning the exterior of the lumen device, cleaning the lumen, or both.

The duration of during which the device is sprayed or flushed can and will vary depending on the device, the type of contaminants to be washed, the degree of contamination (dirtiness) of the device to be cleaned, the parameters used during cleaning such as pressure and volume of cleaning fluid, and the cleaning fluid among other variables or any combination thereof. In essence, a device is sprayed with the cleaning fluid until a predetermined cleanliness endpoint is determined. A cleaning endpoint can be determined while using the washing appliance. Alternatively, cleanliness endpoint can be a predetermined cleanliness endpoint such as an endpoint determined by regulatory authorities. Non-limiting examples of cleanliness standards for re-usable medical devices established by regulatory authorities include:

-   ASTM E2314: Standard Test Method for Determination of Effectiveness     of Cleaning Processes for Reusable Medical Instruments Using a     Microbiologic Method (Simulated Use Test) -   ASTM D7225: Standard Guide for Blood Cleaning Efficiency of     Detergents and Washer-Disinfectors -   ASTM F3208: Standard Guide for Selecting Test Soils for Validation     of Cleaning Methods for Reusable Medical Devices -   ASTM F3172: Standard Guide for Validating Cleaning Processes Used     During the Manufacture of Medical Devices -   Guidelines for reprocessing reusable medical devices, such as     orthoscopic shavers, endoscopes, and suction tubes established by     the FDA

The methods of the instant disclosure can further comprise developing protocols for cleaning a device to reach a desired cleaning endpoint for that specific device. For instance, the duration of wash, the pressure and flow of liquids, the cleaning and drying fluids can all be adjusted to develop a protocol for cleaning the device.

The methods of the instant disclosure can further comprise developing protocols for determining when a cleaning endpoint is reached for a specific device. For instance, a protocol for determining when a cleaning endpoint is reached for a bloody device can comprise assaying used or recirculated cleaning fluid for the presence of blood residue, wherein the device is considered clean when a certain concentration of blood residue, the cleaning endpoint, is reached. Established or newly developed test methods can be used.

One or more than one cleaning fluid can be used in a method of cleaning a certain device. For instance, the device can first be cleaned with water to hydrate dirt and contaminants on and in the device, followed by cleaning with a cleaning fluid appropriate for the device, the contaminants, or both.

Cleaning fluid can and will vary depending on the device, the type of contaminants to be washed, the degree of contamination (dirtiness) of the device to be cleaned, the parameters used during cleaning such as pressure and volume of cleaning fluid, and the cleaning fluid among other variables or any combination thereof. Appropriate cleaning fluids are known in the art. Non-limiting examples of cleaning fluids appropriate for cleaning devices using a method of the instant disclosure include disinfectants, germicides, sanitizers, soaps, enzymes, alcohols, solvents, or any combination thereof among others.

Similarly, drying fluid can and will vary depending on the device, the cleaning fluid(s) used, the parameters used during cleaning such as pressure and volume of cleaning fluid, and the drying fluid among other variables or any combination thereof. Appropriate drying fluids are known in the art. Non-limiting examples of drying fluids appropriate for drying devices using a method of the instant disclosure include air such as ambient air, nitrogen, or oxygen, alcohols, solvents, and any combination thereof among others.

As used herein, the following terms have the meanings ascribed to them unless specified otherwise.

When introducing elements of the present disclosure or the preferred aspects(s) thereof, the articles “a”, “an”, “the” and “said” are intended to mean that there are one or more of the elements. The terms “comprising”, “including” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements.

A “genetically modified” cell refers to a cell in which the nuclear, organellar or extrachromosomal nucleic acid sequences of a cell has been modified, i.e., the cell contains at least one nucleic acid sequence that has been engineered to contain an insertion of at least one nucleotide, a deletion of at least one nucleotide, and/or a substitution of at least one nucleotide.

The terms “genome modification” and “genome editing” refer to processes by which a specific nucleic acid sequence in a genome is changed such that the nucleic acid sequence is modified. The nucleic acid sequence may be modified to comprise an insertion of at least one nucleotide, a deletion of at least one nucleotide, and/or a substitution of at least one nucleotide. The modified nucleic acid sequence is inactivated such that no product is made. Alternatively, the nucleic acid sequence may be modified such that an altered product is made.

The term “heterologous” refers to an entity that is not native to the cell or species of interest.

The terms “nucleic acid” and “polynucleotide” refer to a deoxyribonucleotide or ribonucleotide polymer, in linear or circular conformation. For the purposes of the present disclosure, these terms are not to be construed as limiting with respect to the length of a polymer. The terms may encompass known analogs of natural nucleotides, as well as nucleotides that are modified in the base, sugar and/or phosphate moieties. In general, an analog of a particular nucleotide has the same base-pairing specificity, i.e., an analog of A will base-pair with T. The nucleotides of a nucleic acid or polynucleotide may be linked by phosphodiester, phosphothioate, phosphoramidite, phosphorodiamidate bonds, or combinations thereof.

The term “nucleotide” refers to deoxyribonucleotides or ribonucleotides. The nucleotides may be standard nucleotides (i.e., adenosine, guanosine, cytidine, thymidine, and uridine) or nucleotide analogs. A nucleotide analog refers to a nucleotide having a modified purine or pyrimidine base or a modified ribose moiety. A nucleotide analog may be a naturally occurring nucleotide (e.g., inosine) or a non-naturally occurring nucleotide. Non-limiting examples of modifications on the sugar or base moieties of a nucleotide include the addition (or removal) of acetyl groups, amino groups, carboxyl groups, carboxymethyl groups, hydroxyl groups, methyl groups, phosphoryl groups, and thiol groups, as well as the substitution of the carbon and nitrogen atoms of the bases with other atoms (e.g., 7-deaza purines). Nucleotide analogs also include dideoxy nucleotides, 2′—O—methyl nucleotides, locked nucleic acids (LNA), peptide nucleic acids (PNA), and morpholinos.

The terms “polypeptide” and “protein” are used interchangeably to refer to a polymer of amino acid residues.

As used herein, the terms “target site”, “target sequence”, or “nucleic acid locus” refer to a nucleic acid sequence that defines a portion of a nucleic acid sequence to be modified or edited and to which a homologous recombination composition is engineered to target.

The terms “upstream” and “downstream” refer to locations in a nucleic acid sequence relative to a fixed position. Upstream refers to the region that is 5′ (i.e., near the 5′ end of the strand) to the position, and downstream refers to the region that is 3′ (i.e., near the 3′ end of the strand) to the position.

Techniques for determining nucleic acid and amino acid sequence identity are known in the art. Typically, such techniques include determining the nucleotide sequence of the mRNA for a gene and/or determining the amino acid sequence encoded thereby, and comparing these sequences to a second nucleotide or amino acid sequence. Genomic sequences may also be determined and compared in this fashion. In general, identity refers to an exact nucleotide-to-nucleotide or amino acid-to-amino acid correspondence of two polynucleotides or polypeptide sequences, respectively. Two or more sequences (polynucleotide or amino acid) may be compared by determining their percent identity. The percent identity of two sequences, whether nucleic acid or amino acid sequences, is the number of exact matches between two aligned sequences divided by the length of the shorter sequences and multiplied by 100. An approximate alignment for nucleic acid sequences is provided by the local homology algorithm of Smith and Waterman, Advances in Applied Mathematics 2:482-489 (1981). This algorithm may be applied to amino acid sequences by using the scoring matrix developed by Dayhoff, Atlas of Protein Sequences and Structure, M. O. Dayhoff ed., 5 suppl. 3:353-358, National Biomedical Research Foundation, Washington, D.C., USA, and normalized by Gribskov, Nucl. Acids Res. 14(6):6745-6763 (1986). An exemplary implementation of this algorithm to determine percent identity of a sequence is provided by the Genetics Computer Group (Madison, Wis.) in the “BestFit” utility application. Other suitable programs for calculating the percent identity or similarity between sequences are generally known in the art, for example, another alignment program is BLAST, used with default parameters. For example, BLASTN and BLASTP may be used using the following default parameters: genetic code=standard; filter=none; strand=both; cutoff=60; expect=10; Matrix=BLOSUM62; Descriptions=50 sequences; sort by=HIGH SCORE; Databases=non-redundant, GenBank+EMBL+DDBJ+PDB+GenBank CDS translations+Swiss protein+Spupdate+PIR. Details of these programs may be found on the GenBank website. With respect to sequences described herein, the range of desired degrees of sequence identity is approximately 80% to 100% and any integer value therebetween. Typically the percent identities between sequences are at least 70-75%, preferably 80-82%, more preferably 85-90%, even more preferably 92%, still more preferably 95%, and most preferably 98% sequence identity.

As various changes could be made in the above-described cells and methods without departing from the scope of the invention, it is intended that all matter contained in the above description and in the examples given below, shall be interpreted as illustrative and not in a limiting sense.
